MBRB20H50CT-E3/81

Diode Arrays Overview

The MBRB20H50CT-E3/81 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes high barrier technology for improved high-temperature performance and features a TO-263AB (D2PAK) surface-mount package. The device provides a maximum repetitive peak reverse voltage of 50 V and supports a total average forward rectified current of 20 A, with 10 A per diode. Key electrical characteristics include a low forward voltage drop ranging from 0.55 V to 0.71 V depending on temperature and current conditions, and a maximum reverse leakage current of 100 µA at rated voltage. The component is designed for high-frequency operation and offers high surge capability.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and delivery mode. The E3 suffix indicates consumer grade compliance with lead-free requirements and whisker testing standards. Confirm that the /81 suffix corresponds to the tape and reel packaging format rather than tube packaging. Ensure compatibility with RoHS directives and WEEE regulations as specified in the manufacturer's material category policy before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with a 50 V rating and 10 A per diode capacity is required in a surface-mount D2PAK package. The high barrier technology makes it suitable for applications requiring improved performance at elevated junction temperatures up to 175 °C. Consider the thermal resistance and derating curves for proper heat dissipation design. Verify that the operating frequency and surge current requirements align with the device's specifications for reliable long-term operation.

Diode Arrays Part Context

This part belongs to the MBR(F,B)20HxxCT series of dual common-cathode Schottky rectifiers offered by Vishay. The series encompasses various reverse voltage ratings from 35 V to 60 V, sharing similar mechanical and electrical architectures. The 'B' prefix denotes the TO-263AB surface-mount package variant. These devices are engineered for general-purpose rectification in modern electronic systems where space constraints and thermal efficiency are critical design factors.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRB20H35CT, MBRB20H45CT, and MBRB20H60CT, which share identical pinouts and package dimensions but differ in reverse voltage ratings. Cross-manufacturer equivalents should be evaluated based on matching forward current, reverse voltage, and thermal characteristics.
